Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and more specifically, to a pneumatic clamping device for a CNC roll grinding machine with rapid clamping. Background Technology

[0002] CNC roll grinding machines improve the precision and surface finish of rolls by grinding the roll surface, thereby enhancing the rolling effect. It utilizes a grinding head to grind along the direction of roll rotation, achieving precise control of the grinding process by adjusting the distance and angle between the grinding head and the roll. A pneumatic clamping device for a CNC roll grinding machine is a device that uses pneumatic technology to quickly clamp and release workpieces. The pneumatic system includes an air source (such as an air compressor), pneumatic valves, and cylinders. The air source provides compressed air, the pneumatic valves control the flow and direction of airflow, and the cylinders convert air pressure energy into mechanical energy to clamp and release the workpiece. The clamping mechanism consists of cylinder-driven clamping jaws or centers, used to directly hold the workpiece.

[0003] Among them, the patent with announcement number CN218312710U discloses a grinding machine clamping device, including a clamping mechanism; the clamping mechanism includes a frame, a movable part and a clamping part, the top of the frame is provided with a slide rail and a linear motor, the movable part is slidably connected to the slide rail and fixedly connected to the linear motor;

[0004] In use, this structure moves the clamping part by pushing the movable part with a linear motor, thereby transferring the workpiece. The first clamping arm and the second clamping arm are rotatably connected to the first jaw and the second jaw respectively, so that the first jaw and the second jaw can change from longitudinal clamping to horizontal clamping after clamping the workpiece. However, this structure cannot adapt to irregular and non-standard parts when clamping the workpiece, resulting in low adaptability of the device in use. It is necessary to replace the corresponding jaws in use, which is not convenient. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pneumatic clamping device for CNC roll grinding machines with rapid clamping, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a pneumatic clamping device for a CNC roll grinding machine with quick clamping, including a base plate, on which a clamping assembly is provided;

[0007] The clamping assembly includes a first cylinder disposed at the bottom of the base plate, and the output end of the first cylinder is provided with a push rod for pressing against the workpiece.

[0008] The base plate has several limiting holes on its surface, and each limiting hole is slidably connected to a support rod that presses against the workpiece, and each support rod and the limiting hole are embedded with a spring.

[0009] The first cylinder has a second cylinder mounted on the base plate by bolts on both sides, and each second cylinder has a limit plate at its output end. One end of the limit plate is provided with an elastic clamping plate for clamping the workpiece.

[0010] As can be seen, in the above technical solution, the workpiece is placed on the base plate and lifted by each support rod. The support rod is displaced in the limit hole along the guide of the limit hole due to the weight of the workpiece itself, and the spring is compressed so that the support rod can be reset by the elasticity of the spring itself. This makes it easy to lift irregularly shaped workpieces and ensures the stability of the workpiece when clamped.

[0011] Optionally, in a possible implementation, two inner threaded cylinders are rotatably connected to the base plate, and each inner threaded cylinder is respectively located on both sides of the first cylinder. An extension rod is threadedly connected to the middle of each inner threaded cylinder. A pressure rod is provided at one end of the extension rod. A misalignment opening is provided on one side of each of the two elastic clamps. The elastic clamps and the limiting plate are detachably connected by bolts. The vertical cross-sectional shape of the pressure rod is set to arc shape. The pressure rod is threadedly connected to the extension rod. The extension rod passes through the base plate and extends to the top of the base plate. The plurality of limiting holes are respectively located on both sides of the abutment rod.

[0012] As can be seen, in the above technical solution, the second cylinder drives the limiting plate to move and the elastic clamping plate to move. The elastic clamping plate clamps the outside of the workpiece and deforms under force to fit against the workpiece, which can effectively ensure the stability of the workpiece when clamping. At the same time, the operator holds the pressure rod and drives the extension rod and pressure rod to move by rotating the inner threaded cylinder, so that the pressure rod can clamp the workpiece. In addition, the first cylinder drives the abutment rod to move and press against the workpiece, which can effectively ensure the stability of the workpiece during processing.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, the overall design of the clamping assembly is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the support rod is displaced in the limiting hole by the weight of the workpiece itself and the spring is compressed, so that the support rod can be reset by the elasticity of the spring itself. This makes it easy to lift irregular workpieces and ensures the stability of the workpiece during clamping.

[0015] Furthermore, the elastic clamping plate is displaced by the limiting plate so that the workpiece can lose its limiting position on the base plate, making it convenient to quickly store and retrieve the workpiece and improving the convenience of workpiece processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1 - Figure 4 The pneumatic clamping device for the CNC roll grinding machine shown in the figure uses a clamping assembly on the base plate 1. The workpiece is guided by the weight of the support rod 3 and moves within the limiting hole 2, causing the spring to compress. This allows the support rod 3 to be reset by the elastic drive of the spring, making it easy to lift irregularly shaped workpieces and ensuring the stability of the workpiece during clamping. Furthermore, the elastic clamping plate 11 is moved by the limiting plate 10 so that the workpiece can be released from the limiting on the base plate 1, facilitating quick access to the workpiece and improving the convenience of workpiece processing. The specific structural configuration of the assembly is as follows.

[0025] The clamping assembly includes a first cylinder 4 disposed at the bottom of the base plate 1, and the output end of the first cylinder 4 is provided with a push rod 5 for pressing against the workpiece;

[0026] The surface of the base plate 1 is provided with several limiting holes 2, and each limiting hole 2 is slidably connected with a support rod 3 that presses against the workpiece, and each support rod 3 and the limiting hole 2 are embedded with a spring.

[0027] Both sides of the first cylinder 4 are provided with a second cylinder 9 that is bolted to the base plate 1, and each second cylinder 9 has a limit plate 10 at its output end. One end of the limit plate 10 is provided with an elastic clamping plate 11 for clamping the workpiece.

[0028] Two internal threaded cylinders 6 are rotatably connected to the base plate 1, and each internal threaded cylinder 6 is respectively located on both sides of the first cylinder 4. An extension rod 7 is threadedly connected to the middle of each of the two internal threaded cylinders 6. A pressure rod 8 is provided at one end of the extension rod 7. A misalignment opening 12 is provided on one side of each of the two elastic clamping plates 11. The elastic clamping plates 11 and the limiting plate 10 are detachably connected by bolts. The vertical cross-section of the pressure rod 8 is set to an arc shape. The pressure rod 8 is threadedly connected to the extension rod 7. The extension rod 7 passes through the base plate 1 and extends to the top of the base plate 1. Multiple limiting holes 2 are located on both sides of the abutment rod 5.

[0029] When using the above structure, the staff installs the device at the designated position. When clamping the workpiece, the workpiece is placed on the base plate 1 and lifted by each support rod 3. The support rod 3 is displaced in the limit hole 2 by the weight of the workpiece itself and the spring is compressed, so that the support rod 3 can be reset by the elasticity of the spring itself. This makes it easy to lift irregularly shaped workpieces and ensures the stability of the workpiece clamping.

[0030] Simultaneously, the second cylinder 9 drives the limiting plate 10, causing the limiting plate 10 and the elastic clamping plate 11 to move. The elastic clamping plate 11 clamps the outside of the workpiece, and at the same time, the elastic clamping plate 11 deforms under force and fits against the workpiece, which can effectively ensure the stability of the workpiece during clamping. At the same time, the operator holds the pressure rod 8, and by rotating the inner threaded cylinder 6, the extension rod 7 and the pressure rod 8 are moved, so that the pressure rod 8 can clamp the workpiece. In addition, the first cylinder 4 drives the abutment rod 5 to move and press against the workpiece, which can effectively ensure the stability of the workpiece during processing.

[0031] Unlike existing technologies, this application discloses a pneumatic clamping device for a CNC roll grinding machine with rapid clamping. The support rod 3 is guided by the weight of the workpiece itself and moves within the limiting hole 2, causing the spring to compress. This allows the support rod 3 to be reset by the elastic drive of the spring, making it easy to lift irregularly shaped workpieces and ensuring the stability of the workpiece during clamping. Furthermore, the elastic clamping plate 11 is moved by the limiting plate 10 so that the workpiece can be released from the limiting plate 1, facilitating rapid storage and retrieval of the workpiece and improving the convenience of workpiece processing.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
